The DCI spec was written and published in order to create uniform and compatible digital cinema equipment throughout the U.S. It has been used around the world.

Three companies will handle the compliance testing: CineCert in the U.S., DMC/Keio University in Japan and Media Innovation Center in Italy.

"Through compliance testing, distributors, exhibitors, manufacturers and technology providers will have the assurance that equipment and products have been rigorously reviewed and comply with DCI requirements," the DCI member studios said.

The DCI plan includes all referenced standards of the Society for Motion Picture and Television Engineers.
